Way to check my email database for known spammers?

I recently started using a plugin for my CMS that checks site registration attempts against different spam databases and it’s working quite well! This made me think about my email newsletter database which I know has bad addresses in it - I’d like to know if there is a way to check my list against a database(s) of known spammer addresses, much like the way this plugin for my CMS works. Does anyone know if any such service, either free, or paid, exists?

You probably should use some email verifier prog… there are some free ones around there… in the Netherlands you got the MaxProg… never worked with them before… Maybe you should just google for “Email verifier software” :slight_smile:
